Question

1. explain how the mantle acts like a conveyor belt. how does this lead to plate tectonics?

Explanation:

The mantle has convection currents. Hot material rises, cools, then sinks. This circular motion (like a conveyor belt) moves tectonic plates. Plate tectonics is driven by these mantle movements - plates diverge (at mid - ocean ridges where hot material rises), converge (subduction when cool material sinks), or slide (transform boundaries).
